As a graduate student many years ago in a former life, I had occasion to
to slice rabbit brains, and I found their large size difficult to handle
for transfer to slides. I solved the problem by first embedding the brains
in gelatin and then doing frozen sectioning. There's probably a recipe
somewhere for doing this, but it's not difficult to make one up on your
own.
